Abstract. Let M be a module and N,
K submodules of M. N is called a generalized supplement of K
in M if, M= N + K and N ∩ K
≤ Rad(N). A module M is called a generalized
supplemented module (briefly a GS-module) if any submodule of M has
a generalized supplement in M. Also M
is called a generalized amply supplemented (briefly a GAS-module) if
whenever M = A + B for submodules A, B
of M, then A has a generalized supplement in M
contained in B. It is clear that any supplemented module (amply
supplemented module) is a GS-module (GAS-module). In this paper we
investigate generalizations of these modules. We will show that a module M
is Artinian if and only if M is a δ-GAS-module and satisfies
DCC on generalized δ-supplment and δ-small submodules.
